Chris,
That last paragraph assumes that people (1) know where to look and (2) have hours to spend watching countless channels for announcements. On the other hand, there's also a problem of burying people in so many announcements, surveys, and consultations that people start to tune it all out. This is part of a larger set of communications and "information overload" problems that I'm hoping that WMF will address, particularly during its next Annual Plan.
